2026 Commercial Cleaning Pricing in Bergen County, New Jersey
By Chris, Owner
Published August 10, 2026
Commercial cleaning pricing is driven by the workload inside a facility, not square footage alone. Two similarly sized businesses can receive very different quotes because room mix, traffic, restrooms, access, current condition, and service frequency all change the labor required.
For twice-weekly recurring service, this guide uses budgeting references of $0.18–$0.34 per gross square foot per month for standard offices, $0.28–$0.58 for bounded medical or dental housekeeping, and $0.27–$0.36 for fitness facilities in Bergen’s proprietary sample. All square-foot figures in this guide are shown on a gross-square-foot basis so buyers can compare them using a readily available measurement.
These are starting points rather than Bergen County market averages or facility-specific quotes. The sections below explain how scope, layout, frequency, condition, access, supplies, periodic work, and service expectations affect the final number, and how to compare competing proposals. Unless otherwise noted, prices are shown before New Jersey sales tax.

How is recurring janitorial pricing calculated?
Three questions drive a recurring quote:
How much space is actually being cleaned, and what types of rooms and surfaces are included?
What work is required, how often, and to what standard?
What operating commitments are needed to deliver that scope consistently?
An estimator converts the task list and frequency into labor hours. ISSA’s workloading method identifies spaces, tasks, frequencies, and production rates before calculating labor.1 BSCAI distinguishes task-specific from facility-wide production rates; its example places a medical facility near 2,500 square feet per labor hour.2 APPA uses a similar framework for institutional facilities.3
Production rates are estimating inputs, not prices. Layout, obstruction, room count, floor type, condition, and unit-based tasks all change them.
A useful model is:
Estimated pre-tax customer price = recurring service workload + account-level operating requirements + risk and reliability requirements + provider return.
Recurring workload covers direct cleaning tasks. Account-level requirements include scheduling, supervision, inspections, supply coordination, keys and alarms, callbacks, invoicing, and communication. Many are partly fixed, so a 2,000-square-foot site rarely costs one-fifth of a 10,000-square-foot site. Insurance, backup coverage, replacement capacity, and unusual access or reporting demands add risk and reliability requirements.
Four numbers that are often confused
Worker wage. New Jersey’s minimum wage is $15.92 per hour for most workers in 2026.4 The broader New York–Newark–Jersey City building and grounds cleaning and maintenance occupational group averaged $23.02 per hour in May 2025.5 Both are labor-market context, not customer billing rates.
Provider cost. The cost of delivering the service, including wages or subcontracted service, insurance, supplies, equipment, supervision, and account support.
Customer price. The monthly or per-visit amount stated in the agreement, before sales tax.
Price per square foot. The customer price divided by a stated area figure. It is an output of the estimate and is most useful for budgeting or comparing proposals after their scopes have been normalized.
Why gross square footage is only a starting point
Gross square footage is the facility’s full floor area. Cleanable square footage includes only the space covered by the recurring cleaning scope. Cleanable area can be useful for detailed workloading. Gross area, however, is usually easier for a business buyer to identify consistently from a lease, floor plan, or property record.
For that reason, all square-foot pricing references in this guide are presented on a gross-square-foot basis. Gross square footage still does not determine the quote by itself.
A 4,000-square-foot dental suite, open office, and warehouse bay can create very different workloads even on the same twice-weekly schedule. Square-foot estimates work best for open, repetitive surfaces. They are less reliable where rooms, fixtures, or service points drive labor. A 60-square-foot restroom serving 80 people can take longer to service than 1,000 square feet of open office. Kitchens, exam rooms, locker rooms, showers, stairs, elevators, glass, trash points, and private offices repeat setup and detail work.
Where square-foot pricing breaks down
| Condition | Why area stops predicting the work |
|---|---|
| High restroom or kitchen density | Fixture counts, restocking, and disinfection scale with use rather than floor area |
| Exam, treatment, locker, or shower rooms | Each room is serviced separately, so setup and travel repeat |
| Significant glass, stairs, or elevators | Vertical and hard-surface work is quantified by unit |
| Dense private offices | More doors, waste points, edges, and interruptions |
| Dedicated porter coverage | Priced as staffed hours, not as area |
| Specialty floors and periodic restoration | Run on separate cycles and usually require separate pricing |
| Poor or uncertain condition | Recovery labor is front-loaded and differs from steady-state maintenance |
| Complex access, security, or reporting | Escorts, badging, logs, photographs, and restricted windows add non-cleaning time |
The variables that move price most
Most legitimate quote variance comes from five drivers.
| Priority | Driver | How it changes the quote |
|---|---|---|
| 1 | Scope and task frequency | Changes annual task hours and the periodic-work rotation |
| 2 | Room and fixture mix | Shifts work from area-based to unit-based and lowers effective production rates |
| 3 | Condition and service level | Determines whether the crew is maintaining a stable baseline or recovering a neglected facility |
| 4 | Operating conditions | Adds access, parking, escort, documentation, inspection, or schedule-related time |
| 5 | Provider economics and risk | Reflects labor conditions, route density, supervision, insurance, payment terms, backup capacity, and uncertainty |
Scope and task frequency. “Twice weekly” is a schedule, not a complete scope. The task list should state what happens every visit, weekly, monthly, quarterly, seasonally, and on demand. Matching visit counts can still hide different periodic work.
Room and fixture mix. Restrooms, kitchens, exam rooms, locker rooms, stairs, elevators, private offices, and glass create discrete work. Open areas let a crew move more continuously.
Condition and service level. Maintaining a well-kept facility is different from recovering one with accumulated dust, stained floors, soap buildup, or inconsistent prior service. A separate initial service is often priced before the recurring program begins, with the ongoing rate based on the restored condition. If recovery work is buried in the monthly fee, the provider may absorb an unplanned first-month loss, reduce the service delivered, or seek a later adjustment.
Formal inspections, photo reporting, high appearance standards, daytime attention, and short complaint-response commitments add work even when the task list looks unchanged.
Operating conditions. Parking, access windows, keys, alarms, escorts, weekend coverage, loading docks, and documentation add non-cleaning time, especially in occupied medical and professional facilities.
Provider economics and risk. Route density, supervision, insurance, contract length, payment terms, replacement capacity, and incomplete specifications affect a sustainable quote. Without enough facility information, a provider may price conservatively, exclude work, or assume a later change order.
How does cleaning frequency affect monthly cost?
Recurring scopes normally contain several task layers.
Every-visit tasks include trash, restrooms, traffic-path floors, high-touch surfaces, access, setup, and closeout. Adding a visit repeats most of this work.
Weekly and monthly tasks may include detail dusting, full vacuuming, interior glass, vents, sills, baseboards, partitions, and room rotations. When frequency changes, some of this work can be redistributed rather than repeated during every visit.
Periodic work includes floor refinishing, carpet extraction, high dusting, and seasonal entrance programs. These normally follow separate schedules and may sit outside the recurring monthly fee.
More frequent service usually increases the monthly price because every-visit tasks and mobilization repeat more often. It does not follow one fixed multiplier because weekly, monthly, and periodic tasks may be redistributed, and more frequent service can reduce soil accumulation between visits. If your facility needs a different schedule, price that actual task schedule directly rather than mechanically scaling the twice-weekly ranges in this guide.
Pricing by facility type
Every numeric figure below uses twice-weekly service as the comparison cadence.
| Facility type | Twice-weekly budgeting range per sq. ft. per month | Area basis | Primary qualifications |
|---|---|---|---|
| Professional office | $0.18–$0.34 | Gross sq. ft. | Bergen budgeting reference informed by ISSA office-category guidance; routine recurring scope |
| Medical and dental housekeeping | $0.28–$0.58 | Gross sq. ft. | Bergen budgeting reference informed by ISSA healthcare-category guidance; bounded housekeeping only; clinical responsibilities excluded unless stated |
| Retail and fitness | $0.27–$0.36 | Gross sq. ft. | 22-facility twice-weekly fitness sample; general retail remains site-specific |
| Multi-tenant buildings | No unified range | Component based | Base cleaning plus porter, floors, glass, consumables, seasonal work, and response requirements |
| Warehouse and light industrial | $0.16–$0.40 | Gross sq. ft. | Bergen budgeting reference informed by ISSA industrial-category guidance; routine janitorial scope only |
Source note: ISSA’s monthly category pricing guidance is the starting point for Bergen’s office, medical/healthcare, and industrial/manufacturing references. Bergen applies its own twice-weekly budgeting treatment and expresses the resulting references on a gross-square-foot basis so buyers have one consistent comparison unit. These are Bergen budgeting references, not ISSA-published gross-square-foot or twice-weekly ranges.14
Professional offices, including law and accounting
For twice-weekly routine office cleaning, a broad budgeting reference is $0.18–$0.34 per gross square foot per month, with consumables, periodic floor care, carpet extraction, and specialty glass excluded unless the proposal states otherwise.
Actual office pricing depends on the gross area, open versus enclosed layout, private-office and conference-room density, restrooms, kitchens, occupancy, access, current condition, supply responsibility, and periodic work. A large open plan is generally more efficient to maintain than a smaller office with many rooms, waste points, fixtures, and locked areas.
A walkthrough is usually warranted for larger, multi-floor, mixed-use, or uncertain-condition offices. Smaller single-floor offices with a clear task list can often be quoted from measurements, photographs, and scope information. See Bergen’s Office Cleaning service.
Medical and dental housekeeping
For twice-weekly bounded medical or dental housekeeping, a broad budgeting reference is $0.28–$0.58 per gross square foot per month, with consumables and periodic floor work separate and clinical responsibilities excluded unless expressly contracted.
The range is useful only after the responsibility boundary is clear. CDC distinguishes ordinary housekeeping surfaces, such as floors, walls, and sinks, from clinical-contact surfaces, such as dental-unit switches and light handles.6 Clinical-contact surfaces may require barriers or between-patient cleaning and disinfection under separate clinical procedures.7 OSHA requirements may also apply where occupational exposure to blood or other potentially infectious materials is reasonably anticipated.8
Unless expressly contracted, the recurring housekeeping scope should exclude instrument processing, sterilization, sharps handling, regulated medical waste, between-patient turnover, clinical equipment, undefined blood or body-fluid response, and specialty clinical-contact cleaning.
Bergen’s separate medical-spa sample is narrower and uses gross square footage. Across nine twice-weekly New Jersey facilities ranging from 1,143 to 2,400 gross square feet, the middle 50% of monthly prices was $592–$763, with a median of $644. The middle 50% was $0.38–$0.42 per gross square foot per month, with a median of approximately $0.41.9 The sample covers a narrow medical-spa housekeeping scope and should not be generalized to medical or dental facilities more broadly.
A walkthrough is appropriate when treatment-room responsibilities, clinical-contact surfaces, product requirements, waste boundaries, access, or exposure conditions are unclear. See Bergen’s Medical & Dental Cleaning service.
Retail and fitness facilities
For twice-weekly routine fitness cleaning, Bergen’s proprietary sample of 22 facilities across New Jersey and Connecticut, including locations in Bergen County such as Hackensack, Paramus, and Fort Lee, along with selected comparable markets, produced a middle-50% range of $0.27–$0.36 per gross square foot per month, with a median of approximately $0.31. Facilities ranged from 2,692 to 5,073 gross square feet. The standardized sample assumes customer-provided supplies, includes restrooms, showers, locker rooms, and exercise-equipment cleaning, and excludes periodic floor work.9
Fitness work is more task-dense than a lightly occupied office. Showers, locker rooms, mirrors, equipment, wet floors, odor control, and slip prevention add recurring labor. Several wet areas, complex equipment, weekend access, or detailed floor-care requirements generally justify a walkthrough.
The fitness range should not be applied automatically to general retail. Retail pricing varies materially based on public traffic, operating days, weekend service, restrooms, fitting rooms, glass, food or beverage activity, floor type, waste, seasonal traffic, and whether cleaning occurs during or outside public hours. A low-traffic showroom with one restroom requires a different scope from a busy store with fitting rooms, stock areas, food residue, frequent glass, and daily appearance standards. See Bergen’s Gym & Fitness Cleaning service.
Multi-tenant buildings and common areas
For a multi-tenant building, there is no single defensible all-in square-foot range. The monthly program should be built from the components required by the property rather than compressed into one gross- or cleanable-square-foot figure.
A program may combine:
evening base cleaning;
dedicated porter hours;
public-restroom attendance;
elevators and stairwells;
interior or exterior glass;
periodic carpet and hard-floor work;
consumables;
seasonal entrance work;
tenant requests and tenant turns; and
service-level or rapid-response commitments.
These services use different units and schedules. Evening lobby and corridor cleaning may resemble office work; a daytime porter is reserved labor; public restrooms may need repeated attendance; and floors, glass, tenant turns, and special requests follow separate cycles.
The historical T-1480 award illustrates the limitation. Certain public-building specifications bundled routine cleaning, supplies, porter labor, glass, carpet extraction, and hard-floor work into one procurement structure. Without normalizing the building size, staffing hours, and detailed specification, the result is not a useful current market rate.10
A walkthrough is effectively required to document traffic, common areas, vertical circulation, floor types, tenant boundaries, porter expectations, response requirements, and periodic services. See Bergen’s Property Management Cleaning service.
Warehouses and light-industrial facilities
For twice-weekly routine warehouse or light-industrial janitorial service, a broad budgeting reference is $0.16–$0.40 per gross square foot per month, with consumables and periodic floor service separate and industrial or production-related work excluded unless stated.
Open warehouse floor, offices, restrooms, break rooms, docks, production areas, and other space types should be estimated separately. Large open areas can be efficient to service, while occupied amenity areas, obstructions, long travel distances, production dust, safety restrictions, and dock debris can raise the workload. BSCAI notes that industrial debris, equipment, and travel distance affect manufacturing production rates.2
Routine janitorial scope should exclude machinery, racking, hazardous substances, oil or chemical spills, production cleanup, elevated dust, major debris, and undefined industrial work unless those responsibilities are specifically inspected, scoped, and priced.
A walkthrough should remain standard for warehouse and light-industrial facilities. See Bergen’s Warehouse & Industrial Cleaning service.
What to include when requesting a quote
A useful quote request includes: facility type; gross and cleanable area if available; twice-weekly schedule or requested frequency; room and fixture counts; current condition; access window; supply responsibility; periodic-work expectations; and any existing scope or proposal. You can provide those details through Bergen’s Request a Quote form.
What Bergen’s review of 31 businesses showed
Bergen reviewed customer-facing recurring janitorial pricing for 31 businesses in New Jersey and Connecticut, including locations in Bergen County such as Hackensack, Paramus, and Fort Lee, along with selected comparable markets. The sample includes 22 fitness facilities and nine medical-spa facilities.9
| Segment | N | Frequency | Facility size basis | Middle 50% monthly $/sq. ft. | Median monthly $/sq. ft. |
|---|---|---|---|---|---|
| Fitness | 22 | Twice weekly | 2,692–5,073 gross sq. ft. | $0.27–$0.36 | $0.31 |
| Medical spa | 9 | Twice weekly | 1,143–2,400 gross sq. ft. | $0.38–$0.42 | $0.41 |
Methodology note. Figures are customer-facing monthly recurring prices, pre-tax, on a gross-square-foot basis, with customer-provided supplies and no periodic floor work. Fitness scope includes routine janitorial service, restrooms, showers, locker rooms, and exercise-equipment cleaning. Medical-spa scope covers general, waiting, administrative, and restroom housekeeping; it excludes clinical-specialty cleaning, sharps, regulated medical waste, and clinical equipment processing. Fitness observations span New Jersey and Connecticut, including Bergen County and selected comparable markets; the medical-spa observations are in New Jersey. These are observed standardized prices, not statistically representative market results or a Bergen County market average.9
The sample supports several conclusions:
The two facility types showed different observed unit-price distributions. Medical-spa housekeeping showed a median of approximately $0.41 per gross square foot per month at twice-weekly service, compared with approximately $0.31 for fitness at the same frequency. The difference is consistent with variation in task density and room mix, but the sample does not isolate those effects.
Fitness scope is heavier than a lightly occupied office. Locker rooms, showers, mirrors, and equipment add work, so the fitness sample should not be treated as interchangeable with the office budgeting reference even though both are expressed per gross square foot.
The medical-spa observations are bounded housekeeping. They are not evidence for hospitals, surgery centers, dental operatories, regulated-waste programs, or specialty clinical cleaning.
Smaller sites can show higher unit costs, but this sample does not establish a universal size premium. The observations occupy a limited size band. The direction is consistent with fixed visit and account costs spreading across less area, not with a standard adjustment that should be applied to every smaller facility.
How should a square-foot price be sanity-checked?
A square-foot range is only useful if the resulting monthly total can support the labor, mobilization, supervision, supplies, insurance, account administration, and backup capacity required by the scope.
Where a proposal identifies expected crew size or service hours, compare those hours with the room count, restroom and fixture density, cleanable floor area, every-visit tasks, rotating weekly or monthly work, access and closeout requirements, and periodic-work obligations. A very small implied labor allowance relative to the stated task list should prompt clarification about what is actually included.
A lower bid may reflect a smaller scope, a different square-foot denominator, fewer included tasks, excluded periodic work, better route density, different service expectations, an estimating error, or a price that may be difficult to sustain. The correct response is not to assume the lower provider is wrong. Normalize the proposals, calculate the implied monthly workload, and confirm that the promised scope can be delivered within it.
Why credible quotes can be far apart
Competent providers can still quote different prices because their proposals solve different versions of the job.
| Difference between proposals | Buyer question to resolve |
|---|---|
| Area denominator | Is the price based on gross or cleanable square footage, and are the same areas included? |
| Task list | What happens every visit, weekly, monthly, periodically, and on request? |
| Service cadence | Are the same days, time windows, weekends, and holidays included? |
| Periodic work | Are carpet, hard-floor, high-dusting, and glass services included, amortized, or separate? |
| Supplies and consumables | Who provides chemicals, liners, paper products, soap, equipment, and replacements? |
| Current condition | Does the quote assume a stable baseline or include recovery work? |
| Access and security | Are parking, keys, alarms, escorts, and restricted areas reflected? |
| Quality controls | Are inspections, reporting, complaint response, re-clean terms, and backup coverage defined? |
| Insurance and risk | Are the coverage limits and exposure boundaries comparable? |
| Commercial terms | Do payment terms, contract length, escalators, termination rights, and tax treatment differ? |
| Scope uncertainty | Has each provider seen enough information to price without a large contingency? |
How should buyers compare janitorial proposals?
Rewrite each proposal onto the same basis before comparing the monthly total.
| # | Check | What to confirm |
|---|---|---|
| 1 | Scope | A written task list with every room, surface, and recurring responsibility named |
| 2 | Cadence | Every-visit, weekly, monthly, quarterly, annual, and on-demand tasks |
| 3 | Area basis | Gross or cleanable square footage and excluded areas |
| 4 | Periodic work | Floor, carpet, high-dusting, and glass services included or separately priced |
| 5 | Supplies | Chemicals, equipment, liners, paper, and soap responsibilities |
| 6 | Access | Service window, keys, alarms, escorts, parking, and restricted zones |
| 7 | Insurance and safety | Required certificates, limits, exposure boundaries, and procedures |
| 8 | Quality and response | Inspections, reporting, complaint response, re-clean terms, and backup coverage |
| 9 | Exclusions | Clinical work, hazardous material, machinery, debris, projects, and other boundaries |
| 10 | Sales tax | Whether figures are pre-tax, tax-inclusive, or supported by a valid exemption |
| 11 | Escalator | Annual increase mechanism, index, timing, and cap |
| 12 | Normalized cost | Comparable first-year and second-year totals |
First-year total = 12 × monthly recurring charge + initial service + separately priced periodic work + customer-purchased consumables + applicable sales tax.
Second-year total = 12 × escalated monthly charge + periodic work due in year two + consumables + applicable sales tax.
A lower monthly line can still produce a higher normalized cost once initial work, floor care, consumables, or escalation is included.
For context, the New York–Newark–Jersey City consumer price index rose 4.1% year over year as of June 2026.11 CPI is a consumer basket rather than a cleaning-cost index, so it should be used to understand an index-based escalator clause rather than to predict a provider’s future cleaning costs.
Document scope changes before they affect service or billing. See Bergen’s Janitorial Services.
Frequently asked questions
How much does commercial cleaning cost per square foot?
For twice-weekly budgeting, this guide uses $0.18–$0.34 per gross square foot per month for standard offices, $0.28–$0.58 for bounded medical and dental housekeeping, and $0.16–$0.40 for routine warehouse and light-industrial cleaning. Bergen’s proprietary 22-facility fitness sample across New Jersey and Connecticut, including Bergen County and selected comparable markets, produced $0.27–$0.36 per gross square foot per month. These are budgeting references rather than market averages; actual quotes still depend on scope, room mix, condition, access, supplies, and periodic work.
What is the difference between gross and cleanable square footage?
Gross square footage is the full facility footprint. Cleanable square footage is the area included in the recurring scope. A price divided by gross area usually appears lower, so proposals should use the same denominator before their unit prices are compared.
Why do two companies quote different prices for the same facility?
They may be using different task lists, frequencies, area denominators, periodic-work assumptions, supply responsibilities, access requirements, condition assumptions, quality controls, insurance, or contract terms. The monthly figures become comparable only after those items are aligned.
Does adding another weekly visit increase the price proportionally?
There is no fixed multiplier. Another visit repeats mobilization and every-visit tasks, while weekly and periodic work may be redistributed rather than multiplied. More frequent service can also reduce the soil accumulated between visits.
Why do medical and dental facilities cost more to clean?
They often contain more rooms, sinks, touchpoints, specified products, documentation, and access constraints than a standard office. The price also depends on whether the scope is limited to ordinary housekeeping or extends into clinical-contact responsibilities.
Why can a small office cost more per square foot than a larger office?
Travel, setup, access, supervision, inspections, communication, and billing create fixed or partly fixed account costs. Those costs spread across fewer square feet in a small facility.
Are paper products and cleaning supplies included?
There is no universal convention. The proposal should state who provides cleaning chemicals, equipment, liners, paper products, soap, and other consumables.
Is commercial cleaning taxable in New Jersey?
The published pricing figures exclude sales tax. New Jersey’s general sales-tax rate is 6.625%, and applicable tax is normally added separately unless a valid exemption applies.12,13
When is a walkthrough required?
A walkthrough is usually appropriate for medical or dental facilities with unclear responsibility boundaries, warehouses, multi-tenant buildings, poor or uncertain condition, complex access, or substantial periodic work. Straightforward offices may be quotable from measurements, photographs, and a detailed task list.
What is usually excluded from a recurring janitorial contract?
Common exclusions include floor stripping and refinishing, carpet extraction, exterior and high interior glass, post-construction cleaning, vacancy turns, emergency or restoration work, day porter coverage, tenant turns, and consumables unless the agreement states otherwise.
Getting to a comparable number
A credible comparison requires the same scope, cadence, area basis, inclusions, exclusions, access assumptions, and service expectations. Put those items next to the price and identify what is missing before deciding which proposal is expensive.
